SUBSTANCE: invention relates to fish protective facilities used in diversion facilities. Proposed fish protective facility includes vertical gauze shield installed in inlet part of water intake channel at angle to its longitudinal axis, fish outlet arranged in place of mating of shield with side of channel, and device for creating whirlpool current for washing the shield containing jet guide member and made in form of chambers adjoining outer surface of shield and forming water intake holes over entire depth of water intake channel. Chambers are made cylindrical being formed by surface of shield and jet guide member and are placed in communication through water intake holes formed by edges of shield of adjacent chambers and edges of jet guide members at place of their butt joining. Each chamber is provided with independent fish outlet made in form of vertical perforated pipe arranged coaxially to chamber and communicating by independent fish duct with fish outlet. Inlet part of water intake channel is made with tangential inlet, edge of left side of channel, shield and tangential inlet are arranged in one plane.

EFFECT: improved efficiency of washing of gauze shield and drawing off young fish and trash.

SUBSTANCE: invention relates to devices protecting young fish and preventing their getting into diversion facility. Proposed fish protective facility includes filtering water-separating dam made in form of vertical water-separating wall arranged along water intake channel and separating inlet part of channel from water conduit, device for preliminary drawing off young fish made in form of vertical rod installed for rotation by drive arranged before water-separating wall from its end face part pointed opposite to water flow. Rod is displaced relative to water-separating wall towards water intake channel. Device for preliminary drawing off young fish is furnished with additional means to increase fish draw-off effect, said means being made in from of flat round disks rigidly secured in height of rod coaxially with rod. Disks are installed parallel to each other forming slot water intake channels. End face part of water-separating wall adjoining the rod is provided with slots located opposite to planes of arrangement of disks. Disks are installed for free passing relative to slots. Invention provides higher efficiency of drawing off young fish out limits of zone of influence of diversion facility owing to provision of disks considerably increasing area of contact with surrounding medium and creating powerful circulation flow providing diversion of young fish and trash entrained by water behind outer surface of dam.

EFFECT: provision of effective conditions for drawing off young fish out of limits of zone of influence of diversion facility.

SUBSTANCE: invention is designed to draw off young fish from zone of influence of water diversion front. Method comes to ejecting young fish into intake part of ejecting plant from section of pond with higher concentration of young fish, creating active ejecting working stream in mixing chamber by entraining volume of water containing young fish into stream created by central ejecting hydraulic jet and further conveyance of water-fish mixture along pressure conduit into fish outlet. At the last stage of conveyance young fish is transported into fish outlet under no pressure conditions by forming hydraulic jet angle to trough of fish outlet, young fish being dropped on surface of fish outlet stream. Invention provides effective conditions for drawing off young fish into fish outlet and reduces damage to young fish. If working ejecting stream is preliminarily saturated with atmospheric air, its outer borders are saturated with air in form of finest microbubbles which form boundary layer ("air cushion") at contact with which young fish do not suffer from discomfort and easily take up hydrodynamic pressure built in mixing chamber. Moreover, provision of boundary layer saturated with microbubbles of air makes it possible to considerably reduce value of friction coupling of two streams, main getting from working nozzle and ejecting, containing young fish.

EFFECT: provision of good conditions for letting out young fish into fish outlet, reduced damage of young fish.

SUBSTANCE: invention relates to hydraulic works designed to protect young fish from getting into diversion facilities. Proposed device contains fish retaining shield installed in water channel in tiers in depth of water channel with displacement of each higher tier to side of water intake channel, perforated air duct made in form of guides installed across water channel before shield on bottom of water channel, and trash-and-fish trough connected with fish outlet and arranged in upper part of shield parallel to air duct. Guides are made in form of flat plates rigidly installed at angle to flow in intake channel. Each plate is provided with horizontal axle in its upper part on which additional plate is secured from side of water intake channel for turning. Lower end face end of additional plate is provided with radial baffle whose surface has perforation holes. End face part of additional plates is provided with sector stopper from side of fish outlet, horizontal axles of plates being connected with drive. Additional plates can be perforated.

EFFECT: provision of retaining and bringing young fish out of the limits of influence of diversion facility.
